If ur on island for longer than a few days and u hv access to a kitchen it's worth it to stop here. Only Costco on the island, so plot ur timing to coincide w being nearby.
30 oz. bags of Hershey's Macadamia NutChocolate Kisses can be found here (8 oz bags available elsewhere on the island); makes a great souvenir gift, as they're only available in Hawaii.
Best prices on all your beach gear... Chairs, umbrellas, towels, coolers, snorkels, masks, fins, paddle boards, surf boards, boogie boards... Etc etc etc.
